LM5100CMYX/NOPB

Overview

The LM5100CMYX/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It features two independent non-inverting outputs capable of sourcing and sinking 1 A peak current. The device operates within a supply voltage range of 9 V to 14 V and supports bootstrap voltages up to 118 V. Key electrical parameters include typical rise and fall times of 990 ns and 715 ns, respectively, with a maximum propagation delay of 20 ns. It is housed in an 8-pin MSOP package with an exposed pad and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides dual independent high-side and low-side gate drive channels for half-bridge configurations.
• Delivers 1 A peak output current to efficiently drive power MOSFETs or IGBTs.
• Supports high common-mode transient immunity suitable for high dv/dt switching environments.

Applications

• High-voltage motor control systems
• Industrial power conversion circuits
• Inverter bridge drivers

Procurement Notes

Verify the specific suffix 'CMYX' against the manufacturer's official datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure that the ordering information matches the required RoHS compliance status and industrial temperature grade. Cross-reference the part number with the latest product change notices to avoid obsolete stock issues.

Selection Notes

Select this component when a robust half-bridge driver with 1 A output capability is required for high-voltage applications. It is suitable for designs needing independent channel control and operation within a 9 V to 14 V supply range. Consider the 8-pin MSOP package constraints and thermal dissipation requirements associated with the exposed pad design for proper PCB layout.
